Current WiredTiger stores all hazard pointers on the session in a single array. With the introduction of the weak hazard pointer and the requirement of needing to store a lot of them on sessions we should determine if it is best to store the hazard pointers in a single array with both active and weak pointers, or if it's better to have two separate arrays on the session.
Things to consider:
- Impact on eviction performance
- Complexity of code logic
- Growing and shrinking the hazard pointer arrays
Scope:
- Determine which solution works better and describe the implementation on the follow on ticket:
